actually, EV cars can be turned into interesting track cars.
the batteries weight is smartly spread accross all the chassis which allows homogeneous center of gravity.
the only challenge would be to keep the car low to the ground but will expose the chassis to possible damages.
one other challenge as everybody knows is the cooling required to maintain performance but that will progress for sure.
our car are drinking fuel like crazy on track so this will be the same...but our cars can be re-filled and going back, this will need recovery.
we don't talk about sound or soul, just technical performance.

Boxster Coupe GTS:Taycan GT3 render...
...with V8 4.6 engine from the 918 Spyder?
Taycan stays EV. No petrol engines.
People who think of stuff like that also believe in fairytales and unicorns.

Leawood911:Wonderbar:These vehicles, and their ridiculous 0 to 60 acceleration figures. are getting absurd and even dangerous.
Such a complaint on a Porsche forum is really stunning on so many levels. Are we getting old?
We're at the point where you can be the fastest or just sound like you're the fastest.
The secret of life is to admire without desiring.
Well, blame the electric motor. It's the nature of how their power is delivered.
They have incredible torque from zero rpm onwards, so 0-60 times will be quite amazing.
But electric motors do't run well at higher rpm, so their mid to top range acceleration will suffers.

I think Wonderbar is onto something... EVs will differentiate themselves from high performance petrol cars by delivering absurd 0-60 acceleration times, they already do (Tesla S/X P100D for example).
Many of the EVs have instant acceleration without any lag, so people can imagine how dangerous this can be if you're not used to it. Wouldn't want my kid to drive such a car as a first car.

I can confirm this. When fully accelerating from very slow speeds (or stand still) the 2,5t P100D has a very hard time to go straight. Obviously this is dangerous for those unfamiliar with it

Schmoell - not my experience with my p100d. I can floor it in any conditions without fear and it holds straight at all times. you can feed the traction control working to control optimal power.

Do you have winter tires on yours and drive it in winter time?

schmoell:Yes, it is has winter shoes, which might be the reason.
Yep, some winter tires can't take the torque.
This is why Mercedes AMG for example is using specifically developed winter tires for the E63 S with Mercedes rating, the torque is just insane. Not sure Tesla does the same.

My wife's Model S P100D with Pirelli Sotto Zero 3 winter tires is very easy to control on slippery roads, once one gets used to it. The only learning curve is how to anticipate the effect of braking-regeneration on traction. Anyone knows that too much throttle can cause path-keeping problems, but it's a little new to realize that completely lifting off the throttle causes regen braking to do the same thing. One has to keep a little bit on the throttle pedal to have a neutral "coasting" experience in the most slippery conditions. It's easy to adapt once one knows.

This is probably why Audi with its e-tron SUV has minimized regen upon throttle lift off and prefers to have regen coupled with the conventional hydraulic braking system. This makes it easier for non-EV owners to transition to the Audi. Of course, across time, that will have a diminishing effect.
One key advantage, and one you are no doubt very familiar with, is the speed that an EV traction control/ESP reacts compared with a similar system on an ICE. It is directly communicated to the electric motors while an ICE can only function initially with the closing of throttles, for example, and there is a time delay as the air column in the intake manifold reacts to the changed throttle position. That is enough of a time lag to have the vehicle break traction and affect its stability.

Volvo is doing the same in their PHEV. When you press the brake it first regenerates energy. Pressing stronger or faster changes to breaking and regen. Much more intuitive for non-electrical car driver.
